The author reflects on completing their last half-marathon of the year and an uplifting moment when a fellow runner encouraged them just before the finish. Although it felt like a magical boost of energy, the author considers the possibility that it was actually due to their heart rate returning to a manageable level after a brief rest. This concept ties into the statistical principle of regression toward the mean, where extreme values in measurements tend to normalize upon retesting. The author also announces an upcoming interactive workshop focused on improving communication skills

David Buchanan explores the concept of fault injection as a technique for exploiting vulnerabilities in systems when conventional software bugs are absent. Fault injection involves introducing intentional faults through various means, such as power glitching and electromagnetic pulses, often requiring specialized and costly equipment. However, Buchanan highlights low-budget alternatives, such as using a piezo-electric BBQ igniter for electromagnetic fault injection (EMFI). With the upcoming release of the Nintendo Switch 2 and the lack of software bugs available to exploit, he revisits his interest

A year ago, the author transitioned from charging project fees to day rates, which they describe as a transformative experience. Previously, they struggled with project rates and were influenced by Sanctuary Computer's ideas on value pricing. Although value pricing has gained popularity, the author never felt comfortable with it and found difficulties with project-based pricing. Switching to time-based quoting has alleviated some of the issues they faced, making management simpler and reducing friction. While acknowledging common objections to time-based pricing, they have found the
